A video server controller has an instruction receiver, a command forming unit, and a command issuing unit. The instruction receiver receives the first instruction for recording the material data name of the program material data and the time code indicating the site of interruption of broadcasting of the program material data, and a second instruction for restarting broadcasting of the program material data from the interruption site. The command forming unit, upon receiving the first instruction, stores the material data name and the time code, and upon receiving the CUE UP WITH DATA command as the second instruction, which is standard to the VDCP protocol, the stored material data name and time code are read out. The command issuing unit issues the CUE UP WITH DATA command, the material data name, and the time code to the video server.
